During his June 2013 visit to Poland, Prime Minister Abe Shinzo highlighted the crisis management of the post-3.11 Fukushima Daiichi nuclear power plant as an argument for the sales and promotion of Japanese nuclear technology.1 A few weeks before, the French company Areva mobilized to promote cooperation with Japan Nuclear Fuel Ltd, Atox and Hitachi-GE during French President François Hollande’s visit to Japan.2

These micro signals of another “nuclear renaissance” have provoked some outrage in Japan, for example from former Prime Minister Kan Naoto who branded the trend “disgusting” and even Abe’s wife who openly declared her opposition to the restart of other nuclear plants. In other countries such as Turkey, Saudi Arabia and Vietnam, these efforts have thus far met no success.3

Nevertheless, despite repeated significant leaks of strontium or caesium into the Pacific from Fukushima Daiichi, the “Abenomics boom” has prompted a strong offensive of the nuclear lobby and government plans to reopen Japan’s closed reactors.4 In this context, it is worth remaining alert to the “crisis management” of Fukushima Daiichi (hereafter F1 as the workers have come to call it).

A shortage of personnel

On June 20 and June 24, labor NGOs and civic groups held another round of negotiations with the government concerning working conditions at F1 and for those employed in decontamination work, as well as public health issues related to radiation exposure both for workers and citizens, particularly in Fukushima prefecture.5

Following up on the request they made at the last meeting in February, they again pressed the Ministry of Health and Labor to conduct its own surveys on working conditions at F1 instead of relying almost exclusively on the information provided by TEPCO.6

Nakamura Mitsuo, a labor activist working with day laborers in the yoseba of Sanya who frequently goes to Fukushima, complained that instead of distributing a questionnaire, which workers could send back anonymously (as activists requested), labor inspectors went to F1 and randomly interviewed workers. The few who dared report irregularities were later laid-off.

Graph  17: Personnel required at F1 for the next three years. The bars show the number of workers (starting a little below 14,000 in 2011, ending around 12,000 in 2015) employed in: 1) The maintenance and control of the cold shutdown of the reactor; 2) The diminution of radiation on the site and the treatment of contaminated waters (including the construction of an impermeable wall, etc); 3) The extraction of the spent fuel rods remaining in the cooling pool; 4) The extraction of fuel debris; 5) The treatment and disposal of radioactive solid waste and the decommissioning of the reactors. The pink parts on top of the bars combine the 5 categories. A note mentions the possibility of variations in light of further inquiry.


An officer argued that in a general context of harsh budget restriction because of administrative reform, the Ministry lacks personnel, and it is therefore difficult for the labor bureaus of Futaba (near F1) and Tomioka (near Fukushima Daini/F2) to conduct adequate surveys.

An important question is whether TEPCO has faced similar restriction of personnel. For the last two years, we have repeatedly been told that an average of 3,000 workers enter the site of Fukushima Daiichi every day. But what does that mean exactly?

How many people are now working in F1?

Radiation mapping of Fukushima Daiichi: the red lines show areas with air emissions above 100 mSv per hour; the purple lines between 50 and 100; the yellow lines between 30 and 50; the green lines between 20 and 30; the light blue lines between 10 and 20; the dark blue lines between 0 and 10.


On June 27, TEPCO presented another version of its roadmap for the years to come.7 As TEPCO still refuses to provide the names of its “partners” and subcontractors, it is difficult to get a clear picture of who is doing what, and possible outcomes of their work. But the data presented give an idea of the tremendous tasks that remain to be addressed.

According to the report presented by the government,8 the total task force on the site will not be increased, with TEPCO and its “partners” planning to keep the annual range of workers between 10,000 and 12,000 until 2015. This compares to nearly 14,000 in 2011 and 2012. (See graph 17). The number of those employed in the control of the cold shutdown of the reactors and the treatment of contaminated water9 will progressively decline with the transfer of workers to increase the taskforce carrying out the extraction of the spent fuel rods and fuel 

debris (corium) from the reactors and the cooling pools. These operations are complicated by the damage caused by the hydrogen explosions—which make necessary rebuilding the containment buildings and the cranes to remove the spent fuel and the debris—and the high radiation inside and near the reactors making it even difficult to use robots (a pick radiating 73 Sv per hour was observed at unit-2 in March 2013; a lethal dose starts at around 5 Sv). These operations are expected to start in November 2013 for unit-4, 2015 for unit-3 and 2017 for units 1 and 2; at unit-2, the removal of corium might not start before 2024.10 Decontamination of the entire site will take around 30 years at the most optimistic projection, probably a few decades more.

Graph 19 Number of workers exposed to radiation and those entering the site 19 被ばく者数と新規入域者数の比較 Pink indicates workers entering the site; black the number of workers exposed to 20 mSv or more.

The recently published World Nuclear Industry Status Report 2013, which presents a brilliant synthesis of the situation at F1, notes that priority is given to the removal of the fuel rods from the cooling pool of unit-4, due to the threat of a worst case scenario (as posited at the end of March 2011 by the Chairman of the Japan Atomic Energy Commission, a collapse of the unit-4 pool would require the evacuation of the population within a 250 km perimeter, depending on the winds).11

From July 2012 to April 2013, the total number of people who entered the site increased from around 24,000 to 27,000. As levels of radiation remain high on the site (see the radiation mapping on the aerial photo), it is not surprising that more than 5,000 people have been exposed to a dose exceeding 20 mSv. Even if the rate of increase in those exposed to that level of radiation has decelerated, compared to the situation before 3.11, the numbers are striking: from 2003 to 2009, only 21 workers employed in all Japanese nuclear plants had been exposed to an annual dose above 20 mSV a year.12 This simple comparison helps to convey an idea of the drastic working conditions at Fukushima Daiichi, despite repeated declarations made by TEPCO and the government proclaiming the site safe and stable as a means to assure future restarts of other plants.

Another important point to keep in mind is the use of 20 mSv a year as a practical marker for the management of external radiation.13 By comparison there have been repeated declarations by the ministry of Health and Labor and local authorities in Fukushima prefecture that there is no epidemiological proof of a significant increase of cancer mortality under 100 mSv. Furthermore, TEPCO roadmaps are limited to external radiation and present no data on internal radiation, which can cause much greater damage to health.

Where are the skilled workers?

Another interesting figure (graph 20) indicates that skilled workers have been exposed to higher levels of cumulative radiation. However, the details of this graph are hard to convey, and are not necessarily consistent with the data presented above (showing that around one fourth of the task force has been exposed to a cumulative dose of 20 mSv). (See Graph 20) Ignoring the issue of how the health check follow-up will be implemented for all workers, whatever their skills (and ignoring the fact that a much higher percentage of ordinary workers have been exposed to 5 mSv or more), the comment for the graph focuses on the necessity to train the next generation of skilled workers. This should be indeed a matter of concern, but as we will see below, TEPCO’s policy on this matter is far from coherent.

On the eve of the TEPCO presentation, I met again with T.S., in Iwaki, a city 40 kilometers from F1, where I first met him in June 2011. A native of Tomioka (near F2) where he lived before the disaster, a skilled worker in his thirties, he has been employed for the last ten years by a local contractor of Tōshiba, performing maintenance tasks on the reactor vessels in several plants, mainly for TEPCO at F1 and F2. By mid-March 2011, he had returned to Fukushima Daiichi at the request of his employer, feeling responsible and concerned about what was going on,14 and for the next two years he worked at the site.

T.S. is no longer employed at Fukushima Daiichi, but does decontamination work outside around Tomioka. The salary is better compared with that at F1: in addition to Fukushima prefecture’s basic wage of 6,000 Yen per day, decontamination workers get a 10,000 Yen hazard allowance from the Ministry of Environment; this compared to a maximum of 12,000 Yen per day at F1 (at this level of the subcontracting chain).

Graph 20: Rate of skilled workers exposed to radiation compared to the total taskforce 20 作業員全体及び熟練作業員における被ばく線量区分の比率 (Purple bars: % of skilled workers; yellow bars: % of all workers)

The fact that his cumulative external radiation had reached 70 mSv, and he was found to have 10 mSv of internal radiation at his last WBC check, might have caused him to be sidelined. In any event, TEPCO is trying to reduce the number of those exposed to levels of radiation above 20 mSv under pressure from the Ministries (though this pressure is very limited).

According to Watanabe Hiroyuki, an Iwaki city councilor and a member of the Japan Communist Party, at the end of 2012, many former local subcontractors like the employer of T.S. were informed that TEPCO planned to reduce the taskforce on the site because of “budget restrictions”, so that even level 2 or 3 subcontractors were compelled to lay off many employees. For example, in one case, a company kept only 70 people out of its former taskforce of 300.15 If confirmed, this would be a clear sign that the number of skilled workers at F1 has drastically decreased.

TEPCO webpage (7 July 2013): “We are very sorry, but we are not recruiting personnel for Fukushima Daiichi Nuclear Power Station”

Two workers—let’s call them Wada and Satō—confirm this.16 Wada is a plumber in his fifties, who is usually employed on construction sites. Though he had no experience in nuclear plants, since plumbing is a skill that is required for the maintenance of power plants, he was recruited from his home in Kyūshū in March 2012. He worked at F1 for one year before shifting to a decontamination job outside F1 because he was tired of the wage skimming (pin hane: though told that he would receive 15,000 Yen per day, he never got more than 12,000) and the living conditions were horrendous: the dormitory where he was sent had no kitchen or bathroom, and only a sleeping-bag was provided.

Wada was shocked to find that only one out of five workers had a particular skill applicable to working at F1; he did not mean experience with nuclear plants since he himself had none, but referred to basic skills like nailing or welding as required on construction sites. For example Satō, who worked for three months this spring on the contaminated water tanks near the entrance to F1 before shifting to decontamination work, had been a truck driver before coming to Fukushima.

Until last year, the reactor and turbine makers Tōshiba and Hitachi-GE were the main commanders (moto-uke) of the chain of subcontractors (shita-uke). According to T.S., big construction companies like Kajima, Taisei, Shimizu and Takenaka now control most of the recruitment chain at F1. This means that at the bottom of the chain, the yakuza have increased their control over recruitment, taking over from the small and medium companies that had regular contracts with Tōshiba and Hitachi.

While working at F1, another contract worker told Wada that if he was to place his employer in the chain, it would be more than 12. It is well known that multiple levels of contracting companies implies tremendous wage skimming: for example, for a worker like Wada to be paid 12,000 a day, TEPCO must budget ten times more. To capture the rationale for this elaborate pyramid of subcontractors we would need to review the story of the construction industry since the Meiji period, and observe how it influenced the development of the nuclear industry since the 1970s.

Working on a construction site is itself quite dangerous (in Japan and many industrialized countries, the construction industry has the highest rates of death and injuries). Given the exceptional radiation levels of F1, workers must wear a full protective suit (like Tyvek) and a full-mask in most areas, making it difficult to perform the job well and quickly, which is essential so as to limit radiation exposure as well as to avoid injury. According to the latest TEPCO report, occupational injuries at F1 decreased from a total of 59 in 2011 to 25 in 2012.17 But this depends on the definition of occupational injury.

The labor inspector of the Tomioka Labor Bureau, now relocated in Iwaki, refused to provide any data about claims made by workers employed at F1. This contrasted with the cooperative attitude of his predecessor during my previous visit with similar requests before 3.11.18 Watanabe Hiroyuki comments sharply on the labor bureaus in Tomioka and Futaba: “I don’t think they are willing to help the workers. They obviously protect TEPCO and its partners.”

For example, on 24 March 2011, to install electricity cables inside unit-3, a team of six contract workers was compelled to walk through highly radiated water (another team had refused to enter when they noted emission levels of 400 mSv).19 Soon after, all of them were laid off. With the help of Watanabe, two of them filed an action against Kōei Densetsu, the company right above which commands their employer and which is a subcontractor of TEPCO. As a result of that kamikaze mission, they had cumulated doses of 20 and 80 mSv respectively, so they asked the Tomioka Labor Bureau to certify that this was a radiation accident (hibaku jiko) according to the regulation. But the Bureau responded: “So far they have not gotten sick, so we cannot decide anything”.20

This calls into question the safety of the operations conducted at F1. This might not be so if the multiple levels of subcontracting were not the norm. After 3.11, pressed by the French Nuclear Safety Authority (ASN) on the problems caused by the multiple levels of subcontracting, AREVA and the French Electricity company EDF proposed to reduce to three the number of sub-contracting companies with direct authority for safety issues.21 The Japan Atomic Energy Commission has addressed a similar request: “The government and TEPCO should examine the suitability of conventional employment using second and third subcontractors to ensure workforce in long-term operations in the context [of F1]”.22 The information presented above, however, suggest that this is far from being implemented.

Two contradictory symbols: “Parlor Atom”, a sign promoting a pachinko parlor, a symbol of the ideological captivity of the local population, and a Softbank shop. Since 3.11, Son Masayoshi, chairman of Softbank, has worked to promoted green energy and phase out nuclear power. Tomioka, 29 June 2013(Photo: P. Jobin)

Former F1 cleanup workers and problems of decontamination

Since the skilled workers employed at F1 seem to end in decontamination work, let us conclude with the testimony of Masato (pseudonym), a labor activist in his twenties who formerly organized day laborers in the yoseba of Kamagasaki (Osaka) and who subsequently worked as a decontamination worker in Fukushima to follow the day laborers there. When not employed on decontamination jobs, he offers help at a local union.23

The labor organization of decontamination work shares many similarities with the yoseba. The most obvious characteristic is that the medium age of the workers is around 50 and there is almost no female labor. Then come the less visible parts of the organization of labor:

  • Public bids are now almost entirely controlled by the construction companies at the top (moto uke) and the yakuza at the bottom;
  • Though the Ministry of the Environment only authorizes two levels of subcontracting, in practice, the levels of subcontracting are even more numerous than at F1 and other nuclear plants. Between his own employer and Shimizu Construction, the moto uke, Masato has counted 24 levels;
  • Wage skimming is the norm and many workers only get a tiny portion—if any—of the 10,000 Yen hazard allowance;
  • The majority of workers receive no health insurance benefits from their employer and for many reasons they do not register for the national health insurance system on an individual basis.

The 2012 regulations of the Ministry of the Environment stipulate that below an air emission of 2.5 microSv per hour, the employer has no obligation to provide protection suits (like Tyvek) to the workers.24 This means that decontamination work should be decided on the basis of precise radiation mapping. But in the areas of Tomioka and Iwaki where he has been working, Masato has never seen a worker wearing a Tyvek suit. Following the 2012 regulations, the workers received only a surgical mask, a pair of cotton gloves and a helmet. The core problem is that workers have no access to the radiation mapping made before they enter the zone.

Another tricky point is that the team boss or foreman (one for 5 or 10 workers on average) is the only one with an alarm pocket dosimeter (APD). At the end of the working day, the workers write down or input in a computer the doses recorded by the team boss (between 2 and 7 microSv a day), as if they were the specific doses that each of them had been exposed to. But such collective record cannot but be a very rough estimate of what each worker has individually been exposed to since they may unknowingly approach hot spots while the team boss keeps away.

In contrast, each worker wears a glass badge to record his own individual cumulative dose of air radiation, and it is changed every month. On first entering the decontamination zone, then once every three months, they must go through a whole-body-counter check for internal radiation. They are not, however, given a copy of these results, only informed that “everything is all right, you can keep working.”

The labor organization of decontamination work has therefore many similarities with the structure of labor at F1 and other nuclear plants before 3.11. As we have seen, a major obstacle to the application of labor laws to this population of workers is the hypocrisy of the state ministries and agencies that are supposed to control their employers. Another obstacle is the complete disinterest of big unions like Rengō: the federation Denryoku Sōren only protects the interests of TEPCO employees and other electricity companies while the federation Denki Rengō is concerned only with the employees of reactors and turbine makers like Tōshiba, Hitachi-GE, and IHI. This is why Rengō does not send any delegate to the negotiations with the ministries (mentioned in the introduction).

Even if 50 mSv a year is tolerated, a cumulative dose of 100 mSv over 5 years is the main target, so in practice it is better not to go beyond 20 mSv a year.
